The song comes from Genesis’s first album with Phil Collins as vocalist, all the way back in 1976.
For an example of how proggy it is, this is from the song’s Wikipedia entry:
“The intro is in 7/4, and all 3 verses and 2 choruses are in 4/4 (with one bar of 7/8 ending both choruses, in the little guitar melody).
“The keyboard solo is in the uncommon time signature 13/8, achieved by alternating bars of 7/8 and 6/8, ending with another bar of 6/8 in transition to the interlude verse section (“God always fights…”). This section is again in 13/8, but this time alternating 3 bars of 3/8 with one of 4/8, and ending by skipping the last 4/8 bar in transition to the keyboard melody that follows. This melody is in 13/8 again, but back to the alternation of 7/8 and 6/8.
The outro (“Done me wrong…”) is 16/8, split in 2 bars of 5/8 and one of 6/8.”
Fascinating stuff.
Enjoy.
